Tracked radial stacker with wheels

Abstract

A tracked, portable radial stacker for stockpiling bulk material that includes a linear conveyor having a rear portion and a front portion and being designed to carry bulk material from a low position adjacent the rear portion to a higher position adjacent the front portion. A contact may be disposed adjacent the rear portion of the conveyor and designed to selectively contact the ground to facilitate pivoting of the conveyor. A continuous track system may also be included having a frame to which the conveyor is mounted, the track system including a pair of driven, parallel tracks designed to contact the ground to convey the stacker from one position to another, and to be lifted off the ground when desired. A pair of mid-wheels may be mounted to the frame that are displaceable between a raised position in which they do not contact the ground and a first lowered position in which they engage the ground. A hydraulic wheel displacement system may be included for powering the pair of wheels from the raised position to the first lowered position, the hydraulic wheel displacement system also operable to power the each of the wheels making up the pair of wheels when in the first lowered position to other positions even lower than the first lowered position to lift the tracks off the ground to facilitate operation of the stacker with the tracks raised off of the ground, wherein the hydraulic wheel displacement system operates each of the wheels independently so the wheels can be at different even lower positions to facilitate the stacker being operable on uneven terrain.
